List Child pages with Sling model

-


 List Child pages with Sling model:


Step1: Create a Component with mandatory fields(cq:dialog & component.html)





 

I Created a component with name pageinfo with in that create cq:dialog and rename the .jsp file to .html


Step2: Create a Interface class, Here we created with name PageInfo.java


package com.myproject.aem.core.models;


import com.day.cq.wcm.api.Page;


import java.util.Iterator;

import java.util.List;


public interface PageInfo {

    public List<Page> getPageS();

    public Iterator<Page> getPageChild();

}


Step3:Create Implementation class, Here we created  with name PageInfoImpl.java


package com.myproject.aem.core.models;

import com.day.cq.wcm.api.Page;

import com.day.cq.wcm.api.PageManager;

import org.apache.sling.api.SlingHttpServletRequest;

import org.apache.sling.api.resource.Resource;

import org.apache.sling.models.annotations.DefaultInjectionStrategy;

import org.apache.sling.models.annotations.Model;

import org.apache.sling.models.annotations.injectorspecific.ScriptVariable;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import javax.inject.Inject;

import java.util.ArrayList;

import java.util.Iterator;

import java.util.List;


@Model(adaptables = SlingHttpServletRequest.class, adapters = PageInfo.class, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)

public class PageInfoImpl implements PageInfo{


    private static final Logger LOG = LoggerFactory.getLogger(PageInfoImpl.class);


    @ScriptVariable

    PageManager pageManager;


    @Inject

    Resource resource;



    @Override

    public List<Page> getPageS() {

        List<Page> childPage=new ArrayList<>();

        Page home=pageManager.getPage("/content/myproject/us/en");

        Iterator<Page> childs= home.listChildren();

        while (childs.hasNext()){

            Page page= childs.next();

            childPage.add(page);

        }

        return childPage;

    }


}




Now build the code through IntelliJ or eclipse any other Ide..


Step4: Write Slightly code on html, Here we writing slightly on Paging.html


<sly data-sly-use.child="com.myproject.aem.core.models.PageInfo"> </sly> // here PageInfo is the Interface class Name

<div data-sly-list.item="${child.pageS}">

<p><b> ${item.title}  :  ${item.name} </b></p>

</div>



Now add the component in page and refresh the page you will get all  the child pages (PageTitle: PageName)

  AEM Sightly : Data-sly-list : the most powerful block statement of sightly which iterate the collection return from the slingModel.  Data-sly-list can handle any kind of collection like: Example : <div  data-sly-use. variable_name =“com.aem.package_name.core.models.Interfaceclass_name”></div>// this is used to call the slingModel <div data-sly-list. item =“${ variable_name . InterfaceMethod_Name}”> // item is the default variable provided by Slightly & you can give any name ${ item } </div> *note: Map don’t give ordered list, It gives random list. —> We can control loop’s in slightly using begin, end. Example: <div data-sly-list. item =“${ variable_name .InterfaceMethod_Name @ begin =0, end =3}”>  // the loop gives 4 values ${ item } </div>  —> Slightly provide some methods like: count, even, odd, middle…etc. Example: <div data-sly-list. item =“${ variable_name .InterfaceMethod_Name}”> ${ ite...

Java HashMap

-
  HashMap: HashMap contain data in form of : Keys & Values = Pair(we call it as Pair) Key’s should be Unique and Values can be duplicate. The Keys and Values can be any DataType. To Store Pairs in a variable that should be a “ Map.Entry ” DataType like Object datatype in ArrayList. To read the values from the “ Map.Entry Variable ” we should use methods like: variable.getKey(); variable.getValue() ; * Note:   the name of the Object becomes the name of the HashMap.      ▪  HashMap Declaration : Two ways we can declare HashMap. To Store any DataType of pairs(key, value): HashMap objectName = new HashMap(); Example: HashMap obj = new HashMap();     2.  To Store Required DataType of pairs(key, value):             HashMap <key _DataType, value_DataType>   objectName = new HashMap                <key _DataType, value_DataType> ();  ...

Java Packages

-
Java Packages: A Java Package is a simple kind of a folder which contain a similar   kind of classes, Suppose a classes which are belongs to some functionality will be there in one package the other classes which are belongs to other functionality belongs to other packages. And later if you want to get that class in some other class we will refer that class by using Package Name, So a Java Package is a collection of classes,Interfaces or some files. In realTime the PackageName are like com.ProjectName.CompanyName like this . So If there are two packages with classes:  Package1 {classA, classB,….} & Package2{classX, classY,….}: To access classA from Package2 we need Import & extend keywords Syntax: Import PackageName.className; classX extend classA { // here we can use classA } How to create Sub-Package: Right click on parent package and click on   New—>Package: give name as  “Parent-PackageName.Sub-PackageName” and Finish. These ...
